Different omega-3 concentrations in bran suspension toward the first reproduction time of Artemia sp.

Abstract

The need for Artemia sp. in Indonesia is very high and still relies on imported products. One of the drawbacks of bran suspension is the absence of Omega-3 fatty acids. Omega-3 is proven to accelerate the maturity and reproduction of Artemia sp. The addition of bran suspension with Omega-3 may increase the population of Artemia sp. in culture rapidly. This study aimed was to determine the effect of different concentrations of Omega-3 in rice bran suspension on time of the first reproduction Artemia sp. and to determine the effect of different concentrations of Omega-3 in rice bran suspension on Artemia sp. nauplii production. This study used a Completely Randomized Design which was divided into five treatments and four replications. The concentration of Omega-3 was P1 (3 mL), P2 (4 mL), P3 (5 mL), P4 (6 mL) and using rice bran suspension feed control (P0) 100 gr/mL. Artemia sp. culture was carried out at a density of 100 ind/L. The results showed that the culture of Artemia sp. using bran suspension feed with different concentrations of Omega-3 can affect the first reproduction time of Artemia sp. The fastest first reproduction time of Artemia sp. was produced from cultured using rice bran suspension feed with a concentration of Omega-3 (4 mL) which was 394 hours.
